About this 3.7ct lab-grown oval diamond

This 3.7ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG570374221 or 570374221. Listed at 16 retailers as of October 30, 2026, with prices from $1,268 to $4,037, a $2,769 spread on the same certified stone. Brilliant Earth lists it at $4,037. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
